Ed This is a somewhat confused question and I don't just mean the use of the word "thingy"!
If you check my earlier post where I try to cover all of this, you will see that VTAM is not involved. Presentation space dimensions are a matter for the device or emulator and the application to sort out. The application can present text as best it knows how within whatever the two sets of maximal dimensions that have been imposed by the "device/emulator" allow. Once within the SNA session, you are stuck with the dimensions determined when the session was started. If, somehow, the device or emulator detects that there has been a change of dimensions, a sense code is available to warn the application that all is not as it should be, one of 082A, 082B or 084A. There is, of course, the possibility you are running a 3270 device or emulator which is "non-SNA channel-attached". In this case VTAM is involved because it provides another layer of emulation, mapping CCW-driven data exchanges to the SNA session that the application sees. I tried to work out what might happen if you played fast and loose with presentation space dimension specifications while VTAM was trying to maintain the SNA session. Chaos in the presentation of character strings probably. I would hope that any attempt to effect this change would result in some sort of "reset" which would cause VTAM to terminate the session - with prejudice. Perhaps if I read though the 3174 Functional Description manual carefully I could discover such a "reset".
